Yes honey, we can see that. But please separate fact from fiction
Vampires are mythical creatures. They are not real. Just like Tom&Jerry, Sherlock Holmes and unicorns.
You can't physically be something that doesn't exist. Truth is you can't be anything but human. We get questions like, "Can I turn into a fairy" as well.
Perhaps you are young and have an impressionable mind, and movies like this can have a huge impact. After watching the Wizard of Oz I wanted to fly on a broomstick. I kept one in my room, prayed to it every day... but all that broomstick ever did was sweep the floor, and even then it couldn't do it on its own.
So you can waste your time and energy by trying to do the impossible or you can use that very time and energy to learn about real magic, which you can use to help yourself and others.
The choice is yours
